AUTOMOBZLE-RADIATOR.

Application filed November 17, 1919.

To all whom it may concern:

Be it known that I, om Fnonnnc, a citizen of the United States, residingat Benton Harbor, in the county of Berrien and State of Michigan, haveinvented certain new and useful Improvements in AutomobileRadiators; and.I do declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to automobile-radiators.v

, The main object of this invention is to provide an improvedconstruction which is exceedingly simple and comparatively inexpensive,and which is less easily damaged by extremely cold weather than theradiators of ordinary construction.

A further object is to provide an improved automobile radiator whichincludes a screen which can be very quickly and easily removed for thepurpose of gaining access to the cooling coil for applying a weathershield or for effecting repairs. 7

Other objects and advantages may become apparent'to persons who read thefollowing details of description in connection with the accompanyingdrawings in which,

Figure 1 is a front elevation of my improved radiator.

Fig. 2 is a horizontal sectional view the line 2--2 of Figs. 1 and 4:,

Fig. 3 is a vertical sectional the line 3--3 of Fig. 1.

Fig. 4 is a vertical sectional view along the line 4-4 of Fig. 3. 7

Referring to these drawings in detail, in which similar referencecharacters correspond with similar parts throughout the several views:

The invention includes a hollow frame 1 which is open at its front andrear sides and adapted to be supported on the front part of anautomobile chassis in the usual way, this frame being formed with spacedshoulders 2 and 3 between which is seated a perforated screen 1 of thenovel construction illustrated more clearly in Figs. 2 and 3. The screen1 is preferably formed of a series of horizontal strips or bars 5 and aseries of vertical strips 6, which intersect each other at rightangles,while numerous nozzles 7 are formed or secured between the strips 5 and6, and constitute the perforations of which the screen 4 largelyconsists. A pivot bearing along view along Specification of LettersPatent.

Patented Sept. 6, 1921.

Serial No.. 338,415.

8 is formed on or secured to the top portion of the screen a, and alaterally turned end of a bolt 9 extends through the bearing 8 so as tobe pivotally connected with the'latter. The bolt 9 has one endscrew-threaded and has a wing-nut seated on this threaded end. Apair ofslotted securing lugs 11 are formed on or secured to the upper innersurface of the frame 1, and each bolt 9 extends through one of the slotsof the lugs 11 so that the nuts 10 may engage with the lugs 11 forco-acting therewith and with the shoulders 2 and 3 for removablysecuring the screen 41 in the frame 1 at a position in front of acooling coil or pipe 12, this coil being preferably involute asillustrated in Fig. 3, and has one end communicating with a pipe section13 by means of which it may be connected to a waterjacket' of an engineinthe usual manner. The outer end of the coil 12 is in opencommunication, at 14, with a tank seated on top of theframe 1 andprovided with a pipe connection 16, the latter being adapted forconnection with said water-jacket. It will be seen, therefore, that acirculating system may be completed through a water-jacket, thusconnected with the coil 12 and tank 15.

For the purpose of supporting the middle portion of the tank 15 andaiding in other connections (as will presently appear), a pair of posts1? extend vertically from the lower portion to the upper portion of theframe 1 while crossing the center of this frame. A bar 18 extendshorizontally across the center of the frame and has its ends sooured tothe vertical or upright walls of the frame. The bar 18 is spaced fromthe posts 17 and the series of turns of the coil 12 is arranged betweenthe posts 17 and bar 18. A bar 19 extends across the center of the frame1, and has laterally turned ends which are seated upon the similarlyturned ends of the bar 18, and screws 20 or other appropriate means maybe employed for securing the bars 18 and 19 together and to the frame 1.It will be seen that the bars 18 and 19 have their intermediate portionsspaced from one another and that the coil or pipe 12 is embraced betweenthese two bars. It will also be seen that the upright rods or posts 17are embraced by the bar 18, the latter being formed with suitable loops18' for this purpose at its middle portion. Bolts or screws 21 extendthrough these bars and have screw-threaded engagement with one of them,so that by tightening these the bars screws, the turns of the coils 12are separately clamped by the sections of the bars 18 and 19 between thescrews 21. It will be seen, therefore, that the coil 12 is not only ventvibration of the clamping bars andthe coil supported thereby.

A' considerable space is provided between the removable screen and thecooling coil, and'this space may be utilized for inserting a screen ofpaper, cloth, or other suitable material for protecting the coil 12against extreme cold, and such screen may be very quickly and easilyinserted and removed in consequence of the screen 5 being very uicklyand easily removed, as described in t e foregoing.

In addition to the. important features pointed out in the foregoing, itwill be seen that the form of screen 5, as more clearly shown in Fig. 1,is extremely ornamental and attractive.

'Although I have described this amendment of my invention verySpecifically it is not intended to limit the invention to these exactdetails of construction and arrange: ment, but changes may be madewithin the scope of the inventive ideas as implied and claimed.

quickly and easily removed and replaced without removing or changing theposition of the other turns of the coil. 7

\Vhat I claim asmy invention is:

1. In an automobile radiator, a frame,

water conducting means in said frame, a'

screen in said frame in front of said water conductlng means and havingvertical and transverse strips providing passages of sub-' stantially aneven diameter. for the depth of the screen, and tubes mounted in the airpassages and tapering inwardly toward the water conducting means.

2. In an automobile-radiator, a hollow radiator-frame, water conductingmeans in the radiator frame, a perforated screen normally in front ofsaid water conducting means, a securing lug in the top part of saidradiator-frame and having a slot that opens through one side thereof, ascrew normally extending through said slot and havinga-laterally turnedend and a threaded end, the-laterally turned end being pivoted to thetop part of said screen, and a nut on the threaded end of said bolt,saidbolt'being swingable about its pivotal end to move out. of said slotwhen said nut is loose so that said screw can easily beremoved from theradiator frame. 7

In testimonywhereof I have hereunto set my hand.
